Follow the Leader: This show has a very distinctive part in the Hanna Barbera meddling kids trend. While it clearly is partly following Scooby-Doo, a lot of its variations from Scooby ended up becoming more common in later Scooby installments. So Goober followed Scooby, yet Scooby later followed Goober's lead.
On one base level, Ted is essentially our straight guy leader. Tina is his beta, who is the pretty redhead girl like Daphne. But Tina is a reporter here and not that ditzy. Daphne, of course, in the later years lost her "danger prone" gimmick and her career of choice was a reporter.
While Gillie may look to be drawn like Shaggy, in reality the Goober and Gillie dynamic is actually a predecessor to the Scooby and Scrappy dynamic. Goober would run away like a coward while Gillie stayed behind to take pictures, resulting in Goober rushing back to save Gillie.
The Real After All references would later be utilized in some Scooby productions, although it was featured in Goober episodes years before any Scooby show itself used the trope.
